.PAINT AND PROCESS OF PRODUCING SAM-E-.

SPECIFICATION forming part of Letters ratene No. 780,001, dated January 10, 1905.

An lieation filed January 19 1903. Serial No. 139 615- i f j .P 1 I I /0 (g To all 1117mm it may concern:

Be it known that LWILLIAM A. HALL, a citifor the reason that when thoroughly dried it becomes extremely hard and brittle, so that it is not sufliciently tenacious, and the paints when dry are liable to crack and then peel up or scale off at the edges of the cracks. I have discovered, however, that this brittleness of the soluble or water-glass may be overcome by 'cWgTHTQvYtWasuitable proportion of asbestos in a comminuted form, and by thoroughly stirring or agitating the mixture the asbestos apparently dissolves and entirely disappears as a fiber and gmt the mixture quite a ditferent character, so that when dried it has considerable toughness and flexibility, thus rendering it especially useful as a binding material in paints, either oil-paints or waterpaints, kalsomines, &c.

Asbestos fiber possesses the characteristic of indefinite subdivision, in that each apparent iiber is composed of a multitude of other fibers, the division of which can be carried on indefinitely, and my discovery has developed the fact that when asbestos fiber is mixed with silicate of soda by a thorough agitation it becomes so infinitely subdivided that it is apparently (although not really) dissolved and is in such a state of minute spbdiviS.iQn that it is held in suspension, so as to present all of water.

earthy or mineral base-such as whiting, tale, 5 5- Ec.to givetliepa'intthe proper body or consistency, and the paint may also contain, in addition to the earthy or mineral base and the silicagle of soda and asbestos compolund;1 aniyi suita e i ment or co oring materia an wi also preierably comprise a small percentage of @sirgqilor other ve etablc oil, which when added to the other ingredients saponifies slightly and mixes completely. The asbestos seems to give to the waterglass or silicate of soda asort of felting characteristic, so that the same is to a considerable extent tough or tenacious instead of having the characterise tics of the silicate of soda or water-glass without the asbestos, while the oil, which will for some purposes preferably beadded to the other ingredients in making a paint or enameling composition, still further increases the tenacity or elasticity and strength of the compound when applied as a paint.

The proportion of asbestos fiber to be combined with the silicate of soda or water-glass to produce a desirable binding material for paints or enameling compositions will be about ten parts, by weight, of asbestos to ninety parts of the silicate of soda, although these proportions may be widely varied, according to the purpose for which the paints are to be used. These paints or enameling compositions will preferably contain for each one hundred parts of the silicate of soda and asbestos compound about two hundred parts of an earthy or mineral base, consisting of whiting talc, or their equivalents, preferably in powdered form, and about one hundred parts of Where oil is to be used as an ingredlent of the paint, about fifteen parts of resinoil or other oil may be added to each one hun- TlFad parts oi the silicate of soda and asbestos compound. These proportions, however, (all of which may be understood as being by weight,) may be varied considerably without departing from the spirit of the invention or discovery.

The improved paint or enanieling composi- KOO v tion above described is particularly well ad apted as a coating, or enameling compound for ironmanufactures or other articles where an enameling of a hard though tough or tenacious and durable character is desired.

Having thus described my invention or discovery, I claim and desire to secure by Letters Patent i 1. A liquid paint or enameling composition consisting of, approximately, ninety parts.

silicate of soda or water-glass, ten parts asbestos in a minutely-subdivided condition,

two hundred parts of a powdered earthy or mineral base, as talc or whiting, fifteen parts of a vegetable oil, and one hundred parts of o agitation, then adding to the liquid mixture of silicate of soda or water-glass and asbestos about two hundred parts of an earthy or mineral base, in powdered vform.

' 3. The herein-described process for producing a paint or enameling composition, consisting in mixing with about ninety parts silicate of soda or water-glass about ten parts of asbestos and thoroughly incorporating the ingredients together and minutely subdividing the asbestos fiber in the liquid mixture, by agitation, then adding to the liquid mixture of silicate of soda or water-glass and asbestos about two hundred parts of an earthy or mineral base, in powdered form, and about fifteen parts of a vegetable oil.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM A. HALL.
